What's the harm of going out in foggy weather? What is the reason?

There are foggy days all year round, especially in autumn and winter. Fog, in the eyes of literati, is like a dream and tender as water; But in the eyes of traffic participants (mainly pedestrians, non-motor vehicles and motor vehicle drivers here), it seems to be a "gentle trap". Because of the fog, the visibility is reduced, the line of sight is blurred, and the situation in front and around is not clear, which is prone to danger. At the same time, because the adhesion coefficient of fog and road oil pollution to the ground is reduced, the vehicle is easy to slip and the braking distance is extended, so a little careless travel in foggy days will easily lead to traffic accidents. Therefore, all traffic participants should start from me, do their jobs well, improve their awareness of self-prevention, and strive to create a good traffic environment in foggy days to ensure traffic safety. First, pedestrians in foggy days, pedestrians can not go out without going out, and try to reduce outdoor activities, especially the elderly. Because the combination of fog and pollutants in the weather will bring great harm to people's health. Foggy days can also lead to the reduction of oxygen content in the air, and people will feel chest tightness when breathing, which is particularly easy to increase the incidence of cardiovascular and respiratory diseases. You'd better wear a thin mask unless you have to go out. When on the road, if there is a sidewalk, you must take the sidewalk; There is no sidewalk, so you'd better walk on the left side of the road so that you can see the oncoming traffic clearly. Once the danger is found, you can choose evasive measures in time. According to the old rules, the effect of walking on the right is different, because you don't know when the danger of turning your back on the coming car will happen. If you meet a reckless person (illegal driver) and don't know what's going on (even death), you'll lose! You can't just look at the car when crossing the road (the line of sight is limited). It is important to listen for car horns and roar. When you confirm that there is no car coming, cross the street quickly and leave the wrong place quickly. Second, non-motor vehicles and non-motor vehicles travel in foggy days. If there is a non-motor vehicle lane, you must take the non-motor vehicle lane and not occupy the motor vehicle lane because of the super shortcut; If there is no non-motor vehicle lane, it is best to drive on the left, especially if the bicycle goes up and down from the left. Once in danger, it is more conducive to escape to the side of the road. At the same time, we should control the speed and cross the road carefully like pedestrians, so as not to become ghosts under the wheels! Three, motor vehicles (1) strictly control the speed. When driving in foggy weather, first of all, you should concentrate and drive carefully. Secondly, controlling speed is the key. When the visibility is less than 200m and greater than100m, the speed shall not exceed 60km per hour. When the visibility is less than 100 meters and more than 50 meters, the speed shall not exceed 40 kilometers per hour; When the visibility is less than 50 meters and greater than 30 meters, the speed shall not exceed 20 kilometers per hour; Generally, the sight distance is about 10 meter, and the speed should be controlled below 5 kilometers per hour. When there is dense fog and visibility is extremely low, it is best to drive to the roadside safety zone or parking lot, and then move on after the fog clears or visibility improves. (2) Correct use of lamps and lanterns. Before driving in foggy weather, it is necessary to comprehensively check the lighting device of the vehicle. Turn on anti-fog lights, tail lights, width lights and low beam lights during exercise, and make full use of lights to improve visibility. Need to be reminded that when driving in foggy days, don't use the high beam, because the optical axis of the high beam is high, and the light emitted is reflected by the fog, forming a vast expanse of whiteness in front of the car, but the driver can't see anything. (3) Increase the distance between cars. In foggy days, the road surface is easy to slip, and the braking distance of the car is prolonged. It is necessary to increase the distance between cars during driving, leaving room for handling the situation. Never blindly refer to the front car to prevent rear-end collision. (4) not anxious or dry. When driving in foggy weather, keep calm, don't be impatient, don't accelerate in order to catch up with the preceding car, and don't overtake blindly, so as not to make haste make waste. (5) clean the line of sight. When encountering heavy fog, fog and water droplets condense inside and outside the windshield, which will damage the driver's sight and make the light from the opposite car particularly dazzling. Therefore, in the process of exercise, the water droplets outside the glass are scraped off with a wiper; To deal with the fog inside, you can apply a layer of anti-fog cream in advance, or use warm air in winter, air conditioning in summer and windows in spring and autumn to improve the clarity of sight. (6) honk the horn frequently. In foggy days, the line of sight is not good, and frequent honking can serve as a warning to pedestrians, non-motor vehicles and cars. When you hear the horn of the other car, you should immediately honk your horn to indicate your position.
